COMBINATION PIPE AND NUT WRENCH.

SIPECIFICATION forming part of Letters Patent No. 430,656, dated June24, 1890.

Application filed December 20, 1889. Serial No. 334,381. (No model.)

To all whom it may concern.-

Be it known that I, ERASTUS EDWIN KING, a citizen of the United States,residing at Lees Summit, in the county of Jackson and State of Missouri,have invented a new and useful Combination Pipe and Nut WVrench, ofwhich the following is a specification.

This invention has relation to pipe and nut wrenches; and the objectsand advantages of theinvention, together with the novel featuresthereof, will hereinafter appear, and be particularly pointed out in theappended claims.

Referring to the drawings, Figure 1 is a side elevation of a wrenchconstructed in accordance with my invention. Fig. 2 is asiinilar view,partly in vertical section; and Fig. 3 is a detail in front elevation ofthe lockinglever. Fig. 4 is a detail view to show the claws on the jaws.Fig.5 is a detail of that portion of the stock in which are located therecesses.

Like numerals of reference indicate like parts in all the figures of thedrawings.

1 represents the stock of the wrench, which is rectangular incross-section and terminates at its upper end in a head 2, projected atone side of the stock to form a stationary jaw 3, ending in a beveledhammer-face, and at the opposite side of its stock in a claw 4, curvedto form one member of a pipe-wrench jaw. The stock is reduced near itslower end, form ing a shank, threaded at its lower end, and mounted uponthe shank at about its juncture with the stock is a ferrule 5, fromwhich proects a lug 6. Below the ferrule there is mounted upon the shankan ordinary wooden handle 7, bound in position upon the shank by a nut8, taking over the threaded end of the shank.

9 represents a sliding or movable jaw provided at one end with anopening of a size and shape adapted to fit the stock 1, the shank 10 ofthe .j aw being of rectangular shape in cross-section and arranged faceto face and parallel with the stock 1, and upon its inner face providedwith a series of teeth 11, and terminating at its lower end in a reduced depending stud 12. Having its upper end encircling the stud andits lower end bearing upon the lug 6 is a coiled spring 13, the tendencyof which is to force the movable jaw upward and in contact with thefixed In the side face of the stock 1, and near its lower end, there isformed an irregular recess or seat 14, the lower wall of which isprovided with a semicircular bearing 15, and the upper wall cut away, asat 16.

17 represents a lockingpawl, which is somewhat of an L shape, the angleof the L being provided with a bearing-rib 18*, which rests within theseat 15, and the upper portion of the L being provided with a widenedand toothed head 18, which rests within the cut-away portion 16 at theupper end of the recess 14:, and is normally forced beyond the edge ofthe stock 1, so that the toothed head 18 will intermesh with the teethof the shank 10. The foot of the L-shaped pawl is provided near its endand at one side of its bearing with a lug 19.

20 represents a locking-lever mounted in the recess 14: in rear of thelocking-pawl, and the same comprises a head 21, pressing upon the rearface of the head 18, and a projecting lever portion 22. The parts are sodisposed that the head 21 lies within the angle of the L-shapedlocking-pawl, and said head is pro- ;vided upon its under side with alug 23, corresponding with the lug 19 of the pawl, and

interposed between the head and lever and having its upper and lowerends encircling the lugs 19 and 23 is a light coiled spring 24, which,it will be apparent, serves to press the head 21 of the locking-leveragainst the rear face of the toothed head 18, and consequently normallyprojects said toothed head into mesh with the teeth 11.

25 represents an encircling band or collar, which rests upon the upperedge of the ferrule and extends up and incloses the mechanism described,the lower end of the shank 1O occurring Within the upper end of the bandor collar. Openings are formed through the band or collar and the stockat suitable intervals, and through the same are passed bolts 26. Thelower rear portion of the band or collar is slotted, as at 27, andthrough it projects the extremity of the lever portion of thelockingelever, said extremity being outwardly bent, as at 28.

The operation of my invention will be readily understood from theforegoing description,

but may be briefly stated as follows: In order to spread the jaws, thethumb is employed to draw down upon the bent portion 28 of thelocking-lever, which exerts pressure upon the foot of the L-shapedlocking-pawl, and therefore in rear of its bearing 18*, thus causingsaid pawl to be withdrawn from mesh with the teeth 11 of the shank 10,which shank may now be forced against the tendency of its spring intothe band or collar, and after a snflicient spread has been obtained thelockinglever is released and the parts resume their locked position. Todecrease the spread or width between the jaws, it is simplynecessary topress the locking-lever in the same manner as before described, when thecoiled spring 13 serves to force the movable head toward the stationaryhead, and by releasing the lever the travel of the movable jaw may bestopped at any suitable point.

Opposite the claw portion of the stationary jaw the sliding jaw isprovided with a series of teeth 9* to coact with the curved jaw ingripping pipes, rods, &c.

Having described my invention and its operation, what I claim is 1. In awrench, the combination, with the stock 1, terminating at its upper endin the head 2 and having claw 4, and having the irregular recess 14,terminating at its lower end in the bearing 15 and at its upper end inthe cut-away portion 16, of the L-shaped locking-pawl 17, having thetransversely-toothed head 18, located in the cut-away portion, thebearing 18* at its angle, the foot provided with the lug 19, thelocking-lever 20, terminating at its lower end in the bent handle 22 andat its upper end in the head 21, having the lug 23, the spring24,encircling the lugs,

the shank 10, toothed, as at 11, and provided with the head 9, toothed,as at 9*, and lug 12, the collar 5, having the lug 6, the' coiled spring13, and the band or collar encircling .the shank, stock, and lockingmechanism,

substantially as specified.

2, In a wrench, the combination, with the stock 1, terminating at itsupper end in the stationary head 2, at its lower end in the reducedthreaded shank, and provided between its head and shank with theirregular recess 14, terminating at its lower end in the bearing 15 andat its upper end in the cutaway portion 16, of the L-shaped lockingpawl17, having the transversely toothed head 18, located in the cut-awayportion, the bearing 18* at its angle, the foot provided with the lug19, the locking-lever 20, terminating at its lower end in the benthandle 22 and at its upper end in the head 21, having the lug 23, thespring 24, encircling the lugs, the shank 10, toothed, as at 11, andprovided with the head 9 and lug 12, the collar 5, having the lug 6, thecoiled spring 13, interposed between the lower end of the shank and lug,the encircling-band encircling the stock and shank and the lockingmechanism, the handle 7, mounted on the shank of the stock below thecollar, and the binding-nut 8, threaded on the lower end of said shank,substantially as specified.

3. In a wrench, the combination, with the stock 1, terminating at itsupper end in the head 2, of the L-shaped locking-pawl17,having thetransversely-toothed head 18, the

bearing 18* at its angle, the locking-lever 20,-

terminating at its lower end in the bent handle 22 and at its upper endin the head 21, the spring 24, the shank 10, toothed, as at 11, andprovided with the head 9, the" collar 5, the coiled spring 13, and theband or collar encircling the shank, stock, and lockin g mechanism,substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signaturein presence of two witnesses.
